[kripteks]

I have hd 7850 (SI), performane is medium (but oc is nice), i cant buy new cards for money reason, maybe i can crossfire, i found same card nice price.

I want know if amdgpu support crossfire ?

And for performance, i play old fps game.
Game need support crossfire or crossfire work in back and no need support from game to use all performance cf ?

Crossfire requires tons and tons of work in mesa to split up workloads between GPUs. We have no plans to support it in Linux.
